There is no "women", as a cohesive group, and the very notion of that being the case is asinine. Women don't get along with eachother en-masse, they never have in the history of women being women, and that is the case for very, very good reasons. Because that is the case, 'women' will never control this market, much in the same way that 'men' will never control this market.
You, yourself, may require deposits, and all manner of other things, women, as a whole, do not. There will always be someone younger, hotter, and more permissive out there willing to deal with the occasional missed appointment. She exists without regard to what you rules are, she's likely never heard of you, and as far as she's concerned, you don't exist.
As I've said many times before, you have a vagina, we have money, anything that gets in the way of one being exchanged for the other is bad for business.
